To an whom it may concern:

lie it known that, \Ve,OMAR ll. JEWELL, \VILLIAM M. JEWELL, and Inn. ll. JEwEmL. citizens of the United States, residing at (hi- 3 cage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filtemof which thefollowlug is a specification, reference being had to the accompanying drawings, in which- Figure l is a vertical cross-section of the filtering-tank on llll a: w of Fig-2'. Fig. 2 is a plan view of the pipes for taking up and conveying away the filtered water and for admitting water to the filter while it is'being x 5 washed.

filters forfiltering largequantities of water, and particularly to the kind of filters described by us in the specification forming part of Let- ,ters Patent of the United States granted to 0. H. Jewell and W. M. Jewell, No. 495,573,

dated April 15, 1800.

,Our object is to provide improved'mechanism for agitating the sand while the filter is being washed out, so that the wash-waters may thoroughly cleanse the sand.

In the drawings, Aindicates a filtering-tank of any desired form, niateriah'and construction. To the t p of the tank and rejecting verticallydowsward from the insi 6 thereof is rigidly secnrcda sleeve 13, havigg a gearwh'eel O at the lower end. The gel r-wheel G is preferably formed integral with vthe sleeve 13, as shown in the drawings; but, if desired, it may he rigidly attached to the sleeve inany suitable manner. Through the sleeve B passes a rotating shaft 1), which carricsa verticallymovable gear-wheel E, which is provided with afeather to prevent its rotation upon the shaft I). The gear-wheel E intermeshes with another gear-wheel E, provided with a wheel l by means of which it may be rotated. The various wheels and theshaft D are supported by a frame G at the top of the tank A. U pon 6 is an enlarged detail, being a, partial vertical section of the sleeve with its attached gear-wheel and the driving-shaft.

Our invention relates to improvements in -best shown in- IFig. 1, and mesh witlitho fix 'l gears K K, and thence to the other adjtk' the lower end of the shaft l) is moii'nted horizontal cross-bar H, which iskeyed;lathe shaft D, so as to rotate with it.

it indicates oars, one of which i'srigid-ly -ggy connected to each end of the harlI liyashort upright bar 71'. The bars ll extend river-and? parallel'witli the bar II to form yo cc's. nnexe showh'in' Fig. 1. The shaft ll is solnewlrat longer than the sleeve 13, and its upper end do projects through the frame G andis screw-. threaded, as shown. t r r I if indicates a hand-wheel, which is 'ada'pii led to screw upon the upper end of the shaft"- Dabove the frame G. By this construction 65.1

,the shaft D and bars II Il may heraised l lowered hyoperating the hand-wheel. q 7 K- K KT K. indicate gear-wheels mounted. in a horizontalposition in the yokes-fornred by the bars ll and II, and they are soar ranged as to mesh successively" with one! otherh 'The.geariwheels K K which arc nearest the shaft, are prolonged upward;

The paddles I are centrally secured to the different gears Ksli K K, and their lower ends are broadened to about the shape shown. lly this construc-" tion when the shaft 1) is rotated the cross-$5 bar II is rotated in a horizontal plane, carryv ing with it the gear-wheels K K K K, and the agitating arms or paddles II I, which by the action of the fixed gear 0 upon the inne 90 cent gears, are all rotated about their'rospeetive vertical axes. v i "In use the tank A is partially iilledwith sand or other similar filtering material, and

the object of the paddles I IS toagitat e-thc gsi sand when the filler is. being washed, as will be more fully hereinafter dcscrilmd.- The paddles I are made of such length-that when the bars ll ll and shaft 1) are at their high-' 0st point the lower ends of the paddles will v just clear the sand. If the shaft I) is then rotated, the water abovcthe sand willbaglingsupon each side of the pipe M are tapped valve g is opened tated without materially which is desirable in out the impurities.

shown in Fig. 2, consists of are placed pipes water or for admitting water filter, as the case maybc.

' a numbeiuof horizontal pipes N N N, parallel valves 0 d, one upon each with each other, closed at their outer ends, and provided, like the main pipe, each with a number of strainer-cups m m. The main M is closed at one end and at the other through the wall of the filter and communicates by means of a T- coupling a with y the outer pipe I, as is shown in Figs. 1 and 2. w s

'The "outer pipe? has atits lower end'connected with it by, a T- couplingb two horizontal armsPf P, provided with the cut-01f side of-the T-coupling b. The upright pipe P is connected with the supply-pipe O by means of a T- coupling e,placednear the middle of said upright pipe P, and is provided with cut-oft-valves f placed-,respectively, below and above the sup- -ply-pipe0. fl

The operation ot the filter is as follows: When it is desired toI'filtei-fwaterjthecut-oft the cut-off valves f and c fare closed,2and the cute-oft valveo (I opened.

The water admitted by the supply-pipe O I asses into the pipe Pthroogh the open valve g and-is dischargedinto the filtering-chamher. Passing down through the filtering-sand orother'substance L,'it enters the pipes M N N through the strainer-cups-m m m and is discharged by the pipe M into the pipe P below the closed valve f and thence: through I the open valve rl and the pipe P to any depointer W' at its upper sired place. In the pipe seat R, as shown in- Fig. 4. The valve R is adapted to permit the water to flow through the pipe I" in the direction indicated by the arrowin Fig. 4, but to prevent it from (low- ,ing in the other-direction,

S indicates a pin, which is-sccnred to the valve R at itspivotal point and projects horizontally-through the'side of tho valvc-chzuuher and carries an arm 'l,which is rigidlyattached to the pin S and moved as the valve lt risesor falls. The arm 'l carries avertical rod U upon its outer or free cnd,pivotally attached to it and carrying an index-finger or end. The index-11m 'ger W moves up and down a scale suitably arranged. In the drawings wohave shown I is placed a cheok-valve,consisting of a valve R, hinged at its upper end filter that some very filter, which causosthewatcr to run out'soi'nethe valve .6

the scale marked 'on the side of the tank; but,

if desired, it may be otherwise arranged. As the waler flows through the pipe P in the direction indicated by the arrow in Fig, 4 the valve R riscs,turning the pin S and lowering the arm '1, and with it the vertical arm U and the index-finger 0r pointer \V along the scale X. The greater the, quantity of water flowing through check-valve R will be lifted and the lower the index-finger will fall,thns indicating the volume of water flowing through the filter. he index will in use he so: adjusted that when the check-valve R is closed the indexthe pipe I" the higher the finger or pointer \V will stand at zero in the scale. v

For the purpose of washing out the filter .the filtering tanlc provided with one or more wasl out pipes Y Y. located on'alevel with the top of the filter-sand, as shown in Fig. 1, and provided with suitable stop-valves Z Z and pipes leading to the in Fig. 3. When it is desired filter, the valve f is opened, and d are closed, and the valves Z wash-out pipes opened. into the pipe P downward through the coupling a into the pipes M N N'N, whence it flows through the straiuercups 'm m up through the filter-sand and out through the wash-out pipes Y Y.

tating apparatus is set in motion and the agitating arms or paddles I I are revolved through the filter-sand, as above thoroughly plctc and perfect cleansing thereby, Byopcrating the wheel B as above described the paddles I may be sand or they may be raised entirely out of the sand, if desired. The object of locating to wash out the the valves 9, 0, Z in the moved vertically in the sewer, as shown The water thus flows At the same tune though I TOD the wash-out pipes on a lcvcl withthe top of the sand is to give easy egress lJOll'rQllllPlllltics which by the rotary motion of the water i and filter-sand will accumulate near the-top of the sand and near the circumference of the tank. r i When the filter is cleansed and" ,ie again ready to be set in operation to filtcrwa'tcnthe valves are reset, as above described, for the filte1'ing"proccss, except that the valve (L is first closed and thevalve 0' opened. As it. frequently,happcns after washing out the lino dirt is lct'tfin the what muddy at first, 'by opening; and closing the valve (1 the water filter'ct'liuiuiediatcly after; washing is permitted to' escapo through the pipe 1 ins 'the'lsowor.
